Hawaiian Islands Satellite Interpretation Message
Wed, 22 Sep 2010 13:30:00 -0500
Based on data through 1800 UTC September 22 2010.
Around the main Hawaiian islands lies an east west oriented band of showery clouds that is providing the vast majority of clouds coverage over the islands them selves. The leading edge of this band is just east of Kauai with the west edge extending far to the east northeast of the Big Island. The greatest concentration of clouds is presently in the vicinity of Oahu where skies are mostly cloudy. Cloud tops within this area of are upward to between 10000 and 12000 feet. The cloud are thins out from Maui county eastward.
Over Oahu patches of low clouds are primarily covering eastern and interior sections of the island while most leeward areas are cloud free. As mentioned above Oahu was mostly cloud covered with just a few random breaks seen to the lee of the mountains. Over Molokai low clouds are covering eastern sections of the island while over Lanai patches of low clouds are covering interior sections. Over Maui low clouds are banked up over the slopes of Haleakala as well as over the slopes and summits of the west Maui mountains. Over the Big Island low cloud are banked up over portions of the windward slopes from north Kohala southward through the Hilo and Puna districts. Patches of low clouds can also be seen over portions of the southeast Kau slopes.
The area of low pressure is centered about 350 miles to the south of South Point on the Big Island. The low level center lies just on the west side of the deepest convection. Scattered thunderstorms have been pulsing in this area overnight. Water vapor imagery shows southwest winds in the upper levels of the atmosphere in the vicinity of this low. This is drawing up some thin high cirrus clouds from the tops of the deep convection. This low is moving west at around 10 mph.
Elsewhere in the deep tropics isolated deep convection lies along the ITCZ with the highest concentration in an area from 08°N to 12°N between 143°W and 170°W. Individual cloud clusters are moving off toward the west at around 15 mph.
